SULKY-PLOW.

Specication of Letters Patent.

Patented March 3, 1908.

To all whom it may concern:

Be it known that I, CALVIN R. DAvIs, a resident of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Sulky-Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in sulky plows, the object of the invention being to provide an improved construction and arrangement of two plows in a sulky frame which permits either plow to be elevated and the draft pole to be set at the proper angle to do the. best work in side hill or other uneven ground, and the invention consists in certain novel features of construction and combinations and arrangements of arts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings; Figure l is a perspective view illustrating my improvements. Fig. 2 is a rear elevation. Fig. 3 is a top plan view, and Figs. 4, 5 and 6 are views of details of construction.

A represents a steel arch uniting the several parts of the low, and comprises a steel I-beam with boti ends bent down and se cured to hangers B, B. Lugs are formed on the front of the hangers, which extend forward and form bearings to which the frame bar O is attached by bolts. To the sides of the frame bar C, and about midway between the hangers B, B, and the front corners of the frame bar O, a cross brace D, is securely bolted. This cross brace is made oval in cross section, the object of which will more fully hereinafter a pear.

To the center o arched bar A, and on its lower side, a hanger E is bolted, and the alined holes in the lower ends of the arms of this hanger E is on a line with the openings or bearings in hangers B, B.

A brace F is located at the center of the front section of frame bar O, andextends rearward and is secured to the cross brace D by a hook bolt G, and extends back and connects by a bolt with the hanger E.

A stub pole H is located at one side of the center of the low frame, andis rovided between its en s with a bracket I, w ich latter is secured to the front section of the plow frame O. This bracket I is made with a boss formed on its top side which enters a recess in the pole plate J, and a bolt K asses through the bracket, plate and stub po e, but

edge which engages in a recess in the pole iron M, which latter is securely bolted to the rear end of the stub pole H and prevents the rear end of the stub ole from up and down movement," but at t e same time forms a slide on which the pole may be moved laterally. The plate L extends to the center of the arched bar A and forms a bearing for the curved seat spring N, to which the drivers seat is attached.

A sector O is located on top of, and to the left of the center of the arched bar A and a landing lever P is mounted on the sector O, and extends to the right side of the drivers seat. A link Q is connected to the downwardly proj ecting end of landing lever P and the opposite end of said link is connected to the rearward projection on the pole plate M. The object of this arrangement, is to permit the driver to change the angle of the pole, to take more or less land, as the case may require. This is very necessary in hillside work, where the plow has a tendency to slide down hill and away from the furrow, and with my improvements the wheels may be run at the proper angle to hold the plow in position to take the required width of furrow. The pole R is bolted to the left side of stubpole H and in line with the center of the plow frame. When so set, it is in proper location for a two horse team, but by removing the two bolts which go through the stub pole H and pole brackets S, the pole R may be bolted to the right hand side of the stub pole H, and the pole will be in position for a three horse team, and it will thus be seen that but little time will be lost in changingl the plow for either a two or three horse team.

The plow frame is supported on the wheels V1, mounted on stubs V, and the latter are connected with the plow frame by independent bails T T, and brackets U, U, as will now be explained. Each of the bails is bent into the following form; a straight arm W is bracket U extends upward from the stub axle V and is secured to the bail T by a U- bolt, as shown.

The upper end of each bracket U is connected by a link 8 with its lifting lever 7 more fully hereinafter explained, and the brace 2 which is connected at its lower end to the inner end of axle stub V, extends upward and issecured to the top section of bail T. The extreme upper end of said brace is formed into an arm to which the lifting spring 3 is ypivotally connected at its rear end, the forward end of said spring being connected by a tension bolt 4 to the bracket 5 at the front of the plow frame, it being understood that an independent lifting spring is provided for each plow mounting at both sides of the frame.

Two independent sectors 6 and lifting levers 7 are mounted on the respective side of plow frame bar C, near the front thereof and said levers 7 are connected to the brackets U by links 8, as above explained.

The plow beams 14 carrying plows 15 are attached, one to each of the wrists Y of the bails T by the following` described couplings; a grooved clip 9 is firmly clamped to the wrist Y by a U-bolt 10, and receives a flange at one end of a sleeve 11, the latter being made in two parts and bolted together over the wrist Y, and turns freely without lateral movement. To the upper section of sleeve 11, a rojection 12 is made integral. and the plow eam 14 is securely bolted thereto, so that the plowbeam will be raised with the wrist by which the plow is raised from the furrow, and the wheel will be leveled up to the opposite one.

By means of the lifting levers 7 assisted by the lifting springs 3, the plow bottoms v15 can be elevated with but slight eort on the art of the operator and by means of the ifting levers the plows can be made to run at any depth required.

The low can be adjusted by means of the hand lifting levers to run level on uneven ground.

The cross brace D above referred to as being oval in cross section, lies in the path of movement of the front portions of the plow beams 14, and against which the forward ends of the plow beams will strike when elevated and compel only the rear ends of the beams to move upward.

A clevis 13 is provided at the forward end of each plow beam 14 and connected by the usual draft bar 1 6.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention and hence I would have it understood that I do not 'restrict myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention. Y

Having fully described my invention what I claim as new and desire to secure by Letters-Patent is zM 1. In a plow, the combination with an arch and bearing devices at the ends and also intermediate the ends of said arch, of ybails pivotally supported at itsrespective ends in an end and an intermediate bearing device, a bracket secured between its ends to each bail, carrying wheels, axle stubs for said wheels carried by said brackets, operating levers connected with said brackets, and a plow beam mounted on each bail.
